    Providing sufficient water of appropriate quantity has been one of the most pressing issues in the Indian sub-continent.Poor water supply is normally a surrogate for huge volumes of water being lost through leaks, not being invoiced to customers and irregular water supply. It also seriously affects the financial viability of water utilities through lost revenues and increased operational costs. Bhadravati town of Chandrapur district in Maharashtra is no different from other Indian cities, where lack and loss of water is mundane.

    Under the given situations, Bhadravati Municipal Council took the challenge to ensure water supply system inaccuracies are overcome. Bhadravati Municipal Council drove the mission under the Maharashtra Sujal Nirmal Abhiyan Program. The tender for Water Supply Reforms was bagged by the GIS and engineering solutions provider — ADCC Infocad Ltd.

    What was required

    The mandate was to establish a proper water distribution network and a system for measuring non-revenue water (NRW). Educating the people about surveys, billing systems, and water meters was crucial as it also aimed to identify non-registered connections (NRC) and installing an authorized metering system. ADCC intended at obtaining valid, reliable and credible data of water supply as a whole and in further course, the apt measures to ensure smooth water supply.

    When something new is introduced people don’t accept it; they are rigid and reluctant. We need to make them understand the advantages of accepting change, accepting new technology and how the acceptance will improve their living.

    Modus operandi

    ADCC strategically carried out the project in three phases — the first phase covered the survey analysis. Population survey, bifurcation of institutional data, details of water resources, consumption of water by different beneficiaries, and identifying non-registered connections was done right from the scratch. The mapping activity took place in AutoCAD map software to create attribute tables, similarly data integration in ESRI ArcGIS software to produce thematic maps for decision making. To understand how infrastructure would behave as a system, react to operational strategies, and how it should grow as population and demands increase, hydraulic modelling was done and GIS-based Bentley’s WaterGEMS was deployed for the purpose.

    GIS-based real-time monitoring

    By means of hydraulic modelling, ADCC could recognize the optimization of existing infrastructure (storages, transmission and distribution network) in the areas where there was no water supply to cater the demand of future population, demarcation, and modelling of proposed pipeline networks. This also led to minimization of operation and maintenance cost.

     

    Creating a water supply scheme augmentation, involving meter and service connection, and NRW reduction was the second phase. Consumers were provided temper-proof water meters; the charge is in proportion for the actual amount of water used. Every consumer has been given a unique GIS ID, which carries all the details of the consumer. This GIS-based customized real-time monitoring tool, encouraged the conversion of NRC into authorized ones. House service connection was provided to each house as it ensured 100% leak -proof capacity saving the enormous quantity of water; thus, decreasing the NRW.

    Taking the water supply system to the next level ADCC is planning for phase three, which comprises of smart water network management, smart water billing system, SCADA, and 24×7 water supply operations. ADCC has also proposed an app, which will help in maintaining transparency. It includes all the consumer details and materials used for metering system and photo of the place where the meters were installed.

    ADCC was successful in initiating the complete project and while doing so, it also made sure that it created highest awareness and trained people in learning the GIS-based processes and applications. ADCC ensured Education, Information & Communication to be passed to the councils and locals of Bhadravati.

    Advantage ADCC

    • The entire GIS database related to water supply is in one place and can be updated at any point of time. All the consumers are now uniquely numbered and same reference can be used for further monitoring work
    • Thematic maps and GIS data prepared with this project can help to take necessary decisions at higher authority-levels and for other schemes like sewerage, railways, land authority, etc.
    • A sustainable and a centralized water supply network has been designed for next 30 years
    • Increase in demand for water meters, which in return has increased the revenue
    • Control over leakages and water wastage
